repository

A Java interface that describes how an add-on reads and changes database records through Sankhya's Jape data layer. The SDK generates the implementation, so the developer writes the data operations rather than repetitive database-access code.

In plain words
What is it for?
Use it to create or review the data-access layer for an entity, including CRUD operations, criteria searches, native SQL queries, updates, primary-key searches, and paginated results.
Why use it?
It removes boilerplate database code and provides a consistent place for queries, saves, updates, primary-key lookups, and paging. It also supports parameterised queries, which help avoid SQL injection.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

repository scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Repositório (@Repository) — Addon Studio 2.0

Padrão Repository no SDK Sankhya = abstração simplifica acesso dados. Define interfaces declarativas, SDK gera implementação em compile-time — sem boilerplate, type-safe, protege SQL Injection.

Referência complementar: consulte entity para criar entidades correspondentes.


1. Criando um Repositório

Repositório = interface que estende JapeRepository<ID, T>:

import br.com.sankhya.sdk.data.repository.JapeRepository;
import br.com.sankhya.studio.stereotypes.Repository;

@Repository
public interface VeiculoRepository extends JapeRepository<BigDecimal, Veiculo> {
    // métodos customizados aqui
}
  • BigDecimal → tipo chave primária (primeiro param). PK de tabela nativa Sankhya = BigDecimal; PK de tabela do addon = Integer (ver entity)
  • Veiculo → classe entidade (segundo param)

2. Métodos CRUD Padrão (Herdados)

Método Descrição Lança
save(T entity) Salva ou atualiza entidade Exception
findByPK(ID id) Busca por PK → retorna T (pode ser null — verificar com null-check) Exception
findAll() Retorna todas instâncias Exception
findAll(Pageable pageable) Retorna página com ordenação → Page<T> Exception
delete(T entity) Remove entidade do banco Exception

Atenção: todos os métodos herdados lançam Exception checked. Todo método de serviço ou controller que os chame deve declarar throws Exception na assinatura.

findByPK retorna T (nullable), não Optional<T>. Use null-check manual:

MinhaEntidade e = repository.findByPK(id);
if (e == null) throw new MinhaException("Registro não encontrado: " + id);

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

repository is a skill published in the GitHub repository snk-devcenter/addon-studio (5 stars, last pushed 2d ago), licensed MIT. It adds 205 tokens to every session and 5,467 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
